WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK,
OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
A. Installation work and electrical wiring must be done by qualified person(s)
in accordance with all applicable codes and standards, including firerated construction. Switch power off at service panel and lock the service
disconnecting means to prevent power from being switched on accidentally
during installation.
B. When cutting or drilling into wall or ceiling, do not damage electrical wiring
and other hidden utilities.
C. Ducted fans must always be vented to the outdoors.
D. Sufficient air is needed for proper combustion and exhausting of gases
through the flue (chimney) of fuel burning equipment to prevent back
drafting. Follow the heating equipment manufacturer’s guideline and
safety standards such as those published by the National Fire Protection
Association (NFPA), and the American Society for Heating, Refrigeration
and Air Conditioning Engineers (ASHRAE), and local code authorities.
E. ASHRAE residential ventilation standard 62.2 limits exhaust fans (total) to
a maximum of 15 CFM per 100 square feet of occupiable space, unless a
back drafting test is performed or make-up air is provided. Consult a local
HVAC engineer for make-up air evaluation.

Ducting Requirements
• NEVER reduce the duct size.
• When combining ducts together, the square inch area must reflect the total square inch area of the
ducts being combined.
• Do not use flexible or corrugated duct. This type of duct will restrict airflow and reduce performance.
• Only use smooth, galvanized, metal duct.
• Make the duct run as short and as straight as possible with as few turns as possible.
• Avoid sharp-angled turns. Instead, use smooth, gradual turns such as adjustable elbows or 45 degree
angled turns.
• For duct runs over 20 feet, increase the duct diameter by one inch for every ten feet of duct.
• A 90 degree elbow is equal to 5 feet of duct.
Termination Requirements
• Airflow must not be restricted at the end of the duct run.
• A wall louver or roof jack is required for each duct run.
• Every wall louver or roof jack must include a gravity damper to prevent back drafts.
• Do not use screen wire or spring-loaded doors on wall louvers or roof jacks.
• Do not terminate venting into an attic or chimney.

Installation Details
1) Read all instructions thoroughly before beginning installation. Note: These instructions apply to standard hoods only.
Custom hoods may require additional specification consideration.
2) When installing a wall mount range hood, it is recommended that the bottom edge of the hood be located no more
than 30" above the cooking surface for optimum performance.
3) Select the appropriate installation method.
Method 1 is suitable for applications where the top of the hood (blower outlet(s) location) is accessible after the hood
is mounted on the wall.
Method 2 is suitable for applications where the top of the hood (blower outlet(s) location) is not accessible after the
hood is mounted on the wall.
4) IF THE HOOD IS TO BE “BACK VENTED”, PROCEED DIRECTLY TO STEP 5.
Consult the connection diagrams (on next page) for further details on exhaust outlet placement.
Method 1: Install the duct(s) from the outside of the home down to the location of the exhaust outlet(s) on the top
of the hood allowing room for the transition (if applicable). If a transition is used, install duct down to the
location of the transition outlet plus 1". This will allow the transition to engage 1" inside of duct.
Method 2: Install the duct(s) from the outside of the home to the ceiling over the exhaust outlet(s) on the hood. The
end of the duct(s) should extend 1" below the ceiling.
Use duct tape to seal all joints. A complete listing of available Vent-A-Hood ducting materials is provided on the back
page of this instruction sheet.
Transition heights are as follows:
Single Blower (B100):
6" round duct will connect directly to the top of the hood.
Dual Blower (B200):
8" round duct will connect directly to the top of the hood.
Single and Dual Blower (B100 & B200):
6" round duct will connect directly to the top of the hood; 8” round will
connect directly to the top of the hood. Optional 10" round combination
transition (VP562, sold separately) is 17 1/2" tall.
Two Dual Blowers (Two B200s):
Two 8” round ducts connect directly to the top of the hood. Optional 12”
round combination transition (VP563, sold separately) is 16 1/2” tall.

5) Remove the hood from its packaging and place the back of the hood on the floor or countertop in front of the wall
where it will hang.
6) Remove the shipping tape that is securing the E-Z Clean shield(s) inside the hood. Remove the E-Z Clean shield(s) by
lightly pulling it toward the front of the hood. Gently close the back draft damper(s) from the top side of the hood. To
remove the blower housing(s), unsnap the suitcase latches (one on each side of the housing). The housing(s) should
be pulled forward and gently “tipped” to clear the blower wheel(s) and then out of the hood.
7) Remove the three screws retaining the blower motor(s). Unplug
and remove the motor(s), taking care not to damage the blower
wheel(s). It is not necessary to remove the blower wheel from
the motor.
Warning: Make sure power is off and locked at the service disconnecting
means on the service panel during installation.

• Because the Magic Lung® blower uses centrifugal filtration rather than conventional baffle or mesh filters, the Magic Lung® blower can handle cooking equipment with higher cubic feet per minute (CFM) requirements and can deliver equivalent CFM much more
efficiently than other than other filtration systems. When comparing the Magic Lung® with other blower units made by other manufacturers, use the “Equivalent CFM”.

9) If using a duct cover, carefully remove the knockouts from the top four corners of the hood. Remove the duct cover
from its packaging and remove the mounting screws from the base of the duct cover. Place the duct cover on the top
of the hood and secure it temporarily through the knockout openings using the mounting screws previously removed.
Lift the hood and duct cover assembly to the location on the wall where it will be installed.
Lightly mark the wall with a short, horizontal mark along the bottom edge of the hood. When finished, remove the hood
and duct cover assembly from the wall. Remove the duct cover that was previously installed on the hood and set both
items aside.
10) On the back side of the hood, measure the distance between the bottom edge of the hood and the top edge of the
wood mounting strip. Measure this distance above the horizontal mark made in Step 9 and lightly mark the wall with
a level, horizontal line. Measure where the center (left to right) of the hood will be and mark the upper, horizontal line
on the wall with a short, vertical centerline.
11) Remove the screws inside the top of the back of the hood that retain the wood strip that is recessed in the mounting
channel. Note: Some retaining screws may be located behind the blower(s). Remove the wood mounting strip from
the back of the hood and place the top edge of the strip on the upper, level, horizontal line on the wall. Referencing the
vertical centerline from Step 10, place the mounting strip on the wall so it is centered (left to right) in the space where
the hood will be located. Drill pilot holes in the strip to prevent splitting. Using proper hardware, attach the mounting
strip to at least two wall studs.
12) FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY TO STEP 13. Note: Wall
studs may interfere with back venting installations. Additional framing may be required. It is necessary to cut duct
access hole(s) in the wall prior to installing the hood.
Method 1: Hold the hood on the mounting strip by aligning the channel at the top of the back of the hood over the
wood mounting strip on the wall. Place the appropriate elbow(s) on top of the hood in line with the hood
exhaust collar(s). On the wall, trace around the elbow(s). Remove the hood and elbow(s) from the wall. Cut
around the outside of the traced line(s), avoiding wall studs. Install the duct from the outside of the home
to the opening in the wall. Use duct tape to seal joints.
Method 2: Using the applicable venting accessories and the connection diagrams (previous page) as a guide, install
the duct(s) from the outside of the home to the wall over the exhaust outlet(s) on the hood. The end of the
duct(s) should extend 1" past the wall.
13) Hang the hood on the mounting strip by aligning the channel at the top of the back of the hood over the wood mounting
strip on the wall. While holding the hood in place, mark locations on the mounting strip through the two mounting
holes in the channel at the top of the hood. Some mounting holes may be located behind the blower(s). Remove the
hood and drill 3/32" pilot holes at the center of the marks in the wood strip to prevent splitting.

14) FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE NOT BACK VENTING, PROCEED DIRECTLY TO STEP 15.
Method 1: Place the appropriate elbow(s) on the top of the hood. Elbow(s) should be placed with the non-crimped
end(s) on the inside the collar(s) of the exhaust outlet(s). Use duct tape to seal joints. Lift the hood up to
the wall and hang the hood on the mounting strip, taking care to properly align the duct connection(s)
between the elbow(s) and the duct(s) in the wall. Secure the hood to the mounting strip by installing the
screws (previously removed from the strip in Step 11) into the pilot holes drilled in Step 13. If applicable,
slide the duct cover between the ceiling and the top of the hood back to the wall and attach the duct cover
to the hood through the knockout holes using the mounting screws previously removed in Step 9. Caution
must be taken to avoid scratching the hood or ceiling.
Method 2: Place the appropriate elbow(s) on the top of the hood. Elbow(s) should be placed with the non-crimped
end(s) on the inside the collar(s) of the exhaust outlet(s). Use duct tape to seal joints. If applicable, attach
the duct cover to the hood using the mounting screws previously removed in Step 9. Insert the electrical
wire from the service panel into the electrical wire clamp on each motor box. Tighten the wire clamp(s).
While securing the slack in the wire, lift the hood up to the wall and hang the hood on the mounting strip,
taking care to properly align the duct connection(s) between the elbow(s) on the hood and the duct(s) in
the wall. Secure the hood to the mounting strip by installing the screws (previously removed from the strip
in Step 11) into the pilot holes drilled in Step 13.
SKIP STEP 15. PROCEED DIRECTLY TO STEP 16.
15) If applicable, install the transition on the insides of the exhaust collars and seal with duct tape.
Method 1: Lift the hood up to the wall and hang the hood on the mounting strip, taking care to properly align the
duct connection(s) between the hood and the duct in the ceiling. Secure the hood to the mounting strip by
installing the screws (previously removed from the strip in Step 11) into the pilot holes drilled in Step 13.
Use duct tape to seal joints. Insert the electrical wire from the service panel into the electrical wire clamp
on each motor box. Tighten the wire clamp(s). If applicable, slide the duct cover between the ceiling and
the top of the hood back to the wall and attach the duct cover to the hood through the knockout holes from
inside the hood using the mounting screws previously removed in Step 9. Caution must be taken to avoid
scratching the hood or ceiling.
Method 2: Insert the electrical wire from the service panel into the electrical wire clamp on each motor box. Tighten
the wire clamp(s). Cut a piece of duct for each outlet of sufficient length to meet the duct(s) in the ceiling
allowing room for the transition (if applicable). If a transition is used, cut the duct to reach the transition
outlet plus 1”. This will allow the transition to engage 1” inside of the duct. See page 3 for transition heights.
One end of the duct must be crimped to fit inside the duct in the ceiling. Insert the non-crimped end over
the transition or into the exhaust collar(s) on the top of the hood and seal with duct tape. While securing
the slack in the wire, lift the hood up to the wall and hang the hood on the mounting strip, taking care to
properly align the duct connection(s) between the hood and the duct in the ceiling. Secure the hood to the
mounting strip by installing the screws (previously removed from the strip in Step 11) into the pilot holes
drilled in Step 13.
16) From inside the hood, using UL listed wire nuts, attach the “neutral” wire(s) to the white lead(s), the “hot” wire(s) to
the black lead(s), and the ground wire(s) to the green lead(s) inside the motor box(es).
Warning: Do not operate hood without proper ground connection.
17) Plug the motor(s) into the hood and reinstall the blower motor(s) using the three retaining screws that were previously
removed in Step 7.
18) Replace the blower housing(s) and the blower shield(s). Make sure that the damper(s) open and close smoothly.
19) Refer to the Owner Maintenance Guide Operating Instructions for proper hood operation. Test all blower and light
functions to ensure they are operating properly.
